some problem call js to cut screen.

[55143681]

I use html2canvas.min.js to snap the form.

1.Add javaScript\html2canvas.min.js to serverModule's customFiles.

2.Add  function "canvasSaveAs"  to MainForm's Script.

function canvasSaveAs(uri, filename) {
    var link = document.createElement('a');
    if (typeof link.download === 'string') {
        link.href = uri;
        link.download = filename;
        document.body.appendChild(link);
        link.click();
        document.body.removeChild(link);
    } else {
        window.open(uri);
    }
}

3. call the function from my form.

void __fastcall TUniFormAlterMakePdf2::UniBitBtn1Click(TObject *Sender)
{

String   fName;
fName = "111capture" + FormatDateTime("yyyyMMddhhnnss", Now());
UniPanel1->JSInterface->JSCode(
    "html2canvas(document.querySelector(\"#"+ UniPanel1->JSId +"\")).then(function(canvas) {"
    +"   canvasSaveAs(canvas.toDataURL(), \""+ fName +"\");"
    +    "});"
    );
}

 

Problem:

In my new create project(http),that run normal,

but in my another project(https),that run with nothing,

why?
